Abstract
The semi continuous preparation of emulsion droplets of phase A in phase B, comprises mixing the mixture of the phase A and the phase B by a mixing system having scraping agitators (3a, 3b) with coaxial multiple shafts (2a, 2b) to obtain a dispersion of phase A in phase B with a volume concentration of phase A higher than 74%, and diluting the dispersion by addition of the phase B through a mixing system with the coaxial multiple shafts to obtain the emulsion droplets of the phase A in the phase B. The mixing system with the coaxial multiple shafts has non-scraping agitator. The semi continuous preparation of emulsion droplets of phase A in phase B, comprises mixing the mixture of the phase A and the phase B by a mixing system having scraping agitators (3a, 3b) with coaxial multiple shafts (2a, 2b) to obtain a dispersion of phase A in phase B with a volume concentration of phase A higher than 74%, and diluting the dispersion by addition of the phase B through a mixing system with the coaxial multiple shafts to obtain the emulsion droplets of the phase A in the phase B. The mixing system with the coaxial multiple shafts has non-scraping agitator with a speed of =12 m/s at a time of mixing. The average diameter of the emulsion droplets is controlled by an adjustment of deformation applied at the time of the mixing. The mixing step is carried out at the rate of deformation of 5-150 s -> 1>. The agitator scraping is used at a speed of =2.5 m/s. The scraping and non-scraping agitator is in a rotation or a counter rotation form. A mean velocity of rotation of the scraping agitator is lower in the diluting step than the mixing step. A mean velocity of the non-scraping agitator is higher in the diluting step than the mixing step. The number of revolutions of the scraping agitator at diluting step is five times higher than the mixing step. The number of revolutions of the non-scraping agitator at diluting step is twice the mixing step. The average diameter of the emulsion droplet is lower than 1 micron. The emulsion droplet has polydispersity of lower than 0.2. The phase A is added to the phase B with a mass flow of 0.01 - 3 times mass of the phase B per second. The phase B is added to phase A with a mass flow of 0.0001 - 0.1 times mass of phase A per second in mixing step. The phase A is bitumen or aqueous solution and the phase B is a aqueous solution or bitumen.
